C. SHIrP, a

be controlled, second, inside air circulation must be posslble whendesired, and, third, that outside air can be admitted to the radiatorwhen desired. The above requirements necessitate an apparatus wherebyinside air circulation can be alternately established with that ofsecuring air from the outside of the building, or that the two may beoperated simultaneously in such relative degrees to produce the bestresults in the condition of the air within the building, in

respective of the temperature of the air outside the building. To meetthe above requirements radiator casings heretofore have hadcommunication atthe rear with air ducts leading to the outside thebuilding and on their front sides and near the floor these casings, wereprovided-with inlet orifices through which inside air circulation couldbe established. The openings through the air inlet ducts leading to theoutside of the building and the orifices in the front sides of thecasing were controlled by sepa rate dampers, these dampers in many casesbeing actuated by a single lever, while the readily discernible positionof the front dampers also indicated the relative position of the reardampers. The objections to placing the inlet orifices in front of thecasings and near the floor was, first,-in case of schOol buildings theinsertion of foreign matter into the orifices by the children, and,second, the low position of the orifices permitted the infiowing aircurrents to carry the dust from the floor and deposit same upon theWalls immediately above the radiator casings.

To overcome these previously mentioned objections it has been foundexpedient to remove the an intake orifices from the front sides of thecasings and place them in the back sides of the casings and sutficientlyabove the floor, so that, with the introduction of intervening apronsbetween the orifices and floor, the ingoing air in gaining access to theinterior of the casings is forced to enter from above and at thesides ofthe easings and thus carry along only such dust as may be held insuspension. Placing both.

orifices andtheir controlling dampers in the back sldes of the casings,however, necessitated the introduction of certain means for not onlyactuating said dampers but to disclose at all times their relativeposition.

The present invention relates to certain mechanism whereby both dampersmaybe slmultaneously actuated and their respective positions indicated;and the object of the invention consists in the provision of certainmeans for accomplishing the above result'which is simple inconstruction, efiicient in operation, whereby the dampers may be.-

simultaneousl actuated and their positions indicated to the operatorfrom the front of the radiator casing.

I accomplish the above object of the invention, and such others as mayappear from.

a perusal of the specification and claims, by means of the constructionillustrated in the accompanying drawings, forming a part hereof, inwh1ch- I,

Figure 1 is a fragmentary detail vertical sectional view through asection of a building. wall, radiator casing and air inlet orifices.Fig. 2 is a fragmentary detail vertical sectional view, on the line 2-2in Fig. 1, in which the radiator is omitted. Fig. 3 is an enlarged viewin side elevation of the connection between the vertical indicator rodand guide-plate. Fig. 4 is a front elevation of the construction shownin Fig. 3. Fig. 5 is a top or plan view of the construction shown inFig. 4, the indicator rod being shown in section,

Referring to the drawings, 10 represents the usual and well knownradiator, and 11 the inclosing casing which is formed of sheet metal. Onthe back side of the casing and near the floor the casing communicateswith a wall air inlet ventilating duct 12, the latter being let into thebrick-work or such other material from which the'wall 13 is constructed.The orifice between the casing and duct may be increased or reduced 1nsize by means of a damper which is pivoted 16 to the wall of duct 12.Damper 15 is actuated through the medium or a shifting rod 17 and link18, the rod extend- 5 ing forward and through a slot 19 in the "frontwall of the radiator casing base 20 and is provided with the notches 21adapted to engage the wall of base 20 so that the damper can bepartially or entirely moved to the limit of its travel. Air enteringthrough duct 12 from the outside the building is discharged into casing11 and after passing vertically between the heated coils of the radiatoris discharged into the room through the open top of said casing. Casing11 is provided in the back wall with an orifice 25 through which insideair circulation can be established when desired. Orilice 25 is usuallyclosed, by means of a damper 26, when air duct 12 is entirely open, butthe two openings may be partially open at the same time, in order tosecure proper atmospheric condition within the room by means of theadjustments secured with notches 21, as heretofore described. Since themovement of damper 26 is in a direction at right angles to the generalmovement of rod 17, certain mechanism is interposed to not onlysynchronize the movements of dampers 15 and 26 but to control thedistance of travel of damper 28. To accomplish this result damper 26 isshifted through the medium or a vertically disposed rod 28 carrying atransverse pin 29 in which the ends of said pin rest within slots 30 inyoke 31.

Yoke 33. is also provided with a vertical slot 32 adapted to receive rod28, the extended portions of yoke 81 serving to arrest lateral. movementor said rod. Yoke 3l'is secured to damoer 26, and since the metalcomprising both the damper and walls of the casing is composed or thinmaterial these parts are apt to warp and draw away from red 28, in whichcase slots 30 allow for such movement without causing impingement uponsaid rod to interfere with its normal movement. Damper 28 is moved bymeans of transverse pin 29 engaging the extended portions of yolre 31.See Figs. 3, eland 5.. Operative connection is provided between shiftingrod 17 and vertical rod 28 through the medium of a chain 35, one end orthe latter being secured at a convenient point on the rod 17 trom whencethe chain passes over sheave 36, thence upward and over sheave 37 andthence downward and attaching to the lower end of vertical rod 28, theinitial arrangement and connections of chain 85 being such when damper15 stands so as to entirely close the opening through duct 12, damper28, stands so as to leave orifice as "fully open, and vice versa. Rod 28is provided with an extension member 28 which extends up and slightlyabove the upper edge of casing and the upper end or member 28 can riesan indicator plate 38 whose purpose will be hereinafter described. Rod28 and its member 28 may be lengthened or shortened through the mediumof a sleeve l0 and setscrew ll in order to accommodate the rod tocasings of different heights. Having the above construction in mind,with the several parts occupying the positions shown in Fig. 1, whenshifting rod 17 is moved in the direction indicated by the arrow to opendamper 15 chain 35 is carried along, and chain 35, operating oversheaves 36 and 37, moves rod 28' a suflicient distance vertically tocause damper 26 to close orifice 25, and in reversing the movement ofrod 17 the movements of the associated parts are reversed.

- Sheaves 36 and 37 are mounted in a bracket 89 secured to the rear wallof casing 11.

As before stated, member 28 carries the movable indicator plate 38 whichis brought into full view at the upper limit of its travel, and at thelower limit of travel said-plate is hidden by means of the faceplate ofthe stationary indicator plate 46 secured to the rear wall. oi? casing11 by means of the bolts l7. The stationary indicator plate is usuallysupplied with the word shut and is normally exposed for the reason thatdamper l5 normally stands to close the opening through duct 12, anddamper 26 stands to fully expose orifice 25, which permits unobstructedinside air circulation within the room. Movable indicator plate 88 issupplied with the word open, and when said plate is elevated to bringthe word open into view plate 38 will so cover plate as to obscure theword shut. l/Vhen plate 38 is elevated to expose the word open itindicates that damper 15 is moved to open pas. sageway through duct 12and that damper 26 is moved to close orifice 25.

Having thus fully described my said invention, what l desire to secureby Letters Patent, is

1. The combination, with a steam. radiator casing provided in its backwall with an air inlet opening leading to the outside of the buildingand a second opening communicating with the interior oi the room, adamper -Ior controlling the movement of air through each opening, apush-rod for actuating the damper in the outlet opening for the outsideair, a rod for mounting the damper for controlling'the opening for theinside air, a chain for connecting the two rods together, a sheave forengaging the chain and for changing the direction or travel of one rodto that of the other, and an indicator moving with said dampers, -forindicating the posihd "*h d' t" tion or eac amper wit its a acen ll'LBbopening.

2. The combination, wrth a steam radiator casing provided in its rearwall with an arr inlet opening communicating with the interror or theroom, a sliding damper for connection between the mamas a controllingthe passage of air through said opening, a yoke carried by said'damper,a
